FIG. 15 is a vertical sectional view taken generally along the line 1515 of FIG. 13; and

FIG. 16 is a fragmentary elevational view taken generally along the line 1616 of FIG. 14.

Referring now particularly to FlGS. l, 2 and 3 of the drawings, it will be observed that the reference character 16 designates, generally, a railway car axle which is provided with an axle journal 11 that has at its outer end an end collar 12 which extends radially beyond the bearing surface of the journal 11. The longitudinal axis of rotation of the axle 10 is indicated at 13. The longitudinal axis 13 is employed as a reference base in defining the invention in certain of the claims.

The axle journal 11 extends into a railway car journal box that is indicated, generally, at 14 and it forms an integral part of a side frarne of a railway car truck. The journal box l4 includes a top 15, a bottom 16 and vertical side walls 1'7 and 1S. Positioned within the journal box 1 3 is a journal bearing 19 that rests upon the upper side of the axle journal and is held in position by a wedge 29.

it is desirable to prevent movement of the axle journal 11 out of the journal bearing 19 which tends to take place during the starting or stopping of a train or at any time when there is a change in its speed. It is to provide for guiding the axle journal 11 within the journal box 14 and centering it substantially in the position shown under the journal bearing 15 that this invention is particularly addressed. For this purpose there is provided on the vertical side wall 17 a journal guide support that is indicated, generally, at 23. Preferably the journal guide support 23 is a steel forging and it is welded at 24 2-5 and 26, FIG. 3, to the inner side of the vertical side wall 17. It will be observed that the welds 2d, 25 and 26 are spaced from the central portion of the vertical side wall 17 or at locations outside of the critical zone where heat treatnent is required if welding takes place. The journal guide support .23 is of sufficient length to permit the location of these welds outside of the critical zone. Thus the journal guide support 23 can be applied to journal boxes 14 that are in service without requiring that the frarnes be heat treated or annealed.

A journal guide support, shown generally at 27, is mounted on and secured by welding to the vertical side wall 18. Like the journal guide support 23 it is a steel forging and is similar in all respects except that it is arranged for opposite hand mounting. Since its details or" construction are otherwise identical with those of the journal guide support 23, only the latter will be described in detail herein.

FIGS. 4, 5, 6 and 7 of the drawings show the details of construction of the journal guide support 23. As pointed out above it is formed preferably of a steel forging and it has an elongated lower part 3% which is provided with a depending flange 31. Formed integrally with the elongated part 3 1) are end bridging portions 32 and 33 and an intermediate bridging portion The portions 32, 33 and 34 together with the elongated part provide a groove 35 which extends parallel to the axis 13 of rotation of the railway car axle 1d. The side of the groove 35 opposite the elongated pant 3b is formed by flange portions 36, 37 and 33 that are formed in tegr aily with the bridging portions 32, 33 and 34, respectively. The bottom of the groove 35 is indicated in FIG. 6 at ill, 41 and 42 on the bridging portions 32, 33

and 34, respectively. It will be observed that the bottom 42 of the groove on the intermediate bridging portion 34 is convex and that the bottom of the groove 35 faces away from the axis 13 of rotation of the railway oar axle 1h. The end bridging portion 33 is provided with a flange or end wall while the end bridging portion 32 has a recess 46 formed in the bottom ill for the purposes that will presently be apparent.

Inteiiitting with each of the journal guide supports 23 and 27 is a journal guide that is indicated, generally, at 47. The journal guides 47 are of identical construcion and preferably are formed of press forged bronze. The details of construction are shown in F168. 8, 9 and 10 of the drawings. It will be observed that the journal guide 47 is provided with a bearing face 4% along one side which is juxtaposed to the surf-ace of the axle journal 1 1. As shown in FIG. 1 the bearing faces 48 are located at diametrically opposite sides of the axle journal 11 in a horizontal plane through the axis 13 of rotation. Projections 49 are formed integrally on the other side of the journal guide 47 and they extend into the groove 35 previously described as being formed in the respective guide supports. The projections 4-9 are positioned between end sections 50 of the journal guide 47 and an intermediate section 51 which carry on one side the bearing face d3 previously referred to. Ribs 5-2 extend between the end sections 5t) and the intermediate section 51 and a vertical groove 53 may be provided midway the ends of the intermediate section 51 in the bearing face 48. Side Walls 54 are formed integrally with the journal guide 47 and support the projections 49.

Since the projections 49 extend into the groove '35 in the journal guide support 2 3 and the bearing face 48 is juxtaposed to the axle journal 11, the surf-aces 55 of the projections 49 face toward the axle journal 11 or toward its axis 13 of rotation. These surfaces 55 are beveled as indicated at 56 and 57 for a purpose that presently will be apparent.

It will now be understood that the bottom and sides of the groove 35 extending lengthwise of the journal guide support 23 and the surfaces 55 on the projections 49 define what can be considered as an aperture which extends parallel to the side wall 17 for example, and longitudinally of the axle journal 11 and parallel to its axis 13 of rotation. Advantage is taken of the provision of this aperture for inserting a flexible resilient elongated key 59 therein as shown in FIG. 2 of the drawings. The key 59 itself is shown in FIGS. :11 and 12. It is provided with a rounded end 61 to facilitate insertion in the aper ture previously described. In order to further facilitate its insertion the intermediate bridging portion 3 4 is provided with the convex bottom 42 and each of the projections 49 is provided with the beveled surface 56 or 57 one or the other of which may be engaged by the rounded end 60 of the key 59 depending upon which way the journal guide 4-7 is applied to the journal guide support 23. 1

Referring again to FIG. 2, it will be observed that the key 59 is inserted in an undulating manner due to the fact that the bottom of the groove 35 formed by the central portion of the surface 42 is offset from the surfaces 4-0 and 41 toward the respective side wall 17 or 18, as shown in FIGS. 2 and 6 of the drawings, and for this reason and since it is resilient, being formed prefon ably of spring steel, it provides a holding biasing action to secure the journal guide 47 in position in the journal guide support 25. The extent that the key 59 can be inserted in the aperture along the bottom of the groove 35 is controlled, in part, by the flange or end wall 45.

In order to prevent inadvertent or accidental withdrawal of the key 59 it is provided, as shown in FIG. 11, with a slot 61 in which a key lock 62 is positioned. It will be noted that the key lock 62 extends from opposite sides of the key 5 9 and that one side, as shown in FIG. 2, is arranged to interfit with the recess 46. In order to withdraw the key 59, as shown in the lower part of FIG. 2, it is necessary to spring the key 59 toward the respective side wall, for example the wall 13, in order to clear the key lock #62 from the recess 46. Then a suitable tool can be inserted in an aperture 63 near the outer end of the key 59 and sufficient tension be applied to withdraw it.

in operation, with the axle journal 11 removed, the glide supports 23 and 27 are properly located along the vertical side walls 17 and 13, respectively, of the journal box 14 and then are welded in place in a manner previously described. Since the welding takes place away from the central portions of the side walls 17 and 1 8 and particularly from the central portion of the side Wall 17, it is unnecessary to heat treat the car side frame after the journal guide supports 23 and 27 have been welded in. position.

Next the tear side frames can bassembled with the axle journals 11 but without the journal bearing 19 and wedge 211 The journal guides 47 can be inserted over the end collar 12 and the upper surface of the axle journal 1-1 and then moved downwardly on either side into position in the respective journal guide support 23 or 27. This is permit-ted since the elongated part of the journal guide support 23 extends only along the bottom, there being openings between the intermediate bridging portion 34 and the bridging portions 32 and 33 spaced from its ends. The projections 49 enter these openings and the journal guide 4:7 is properly located. Then the key 5@ is inserted in the aperture along the bottom of the groove 3'5, previously described, until the rounded end 6t} engages the flange or end wall 45. The end bridging portion 3 2 is beveled, as indicated at 64, in order to facilitate the passage of the key lock 62 when the key 59 is inserted. When the key 59 is inserted, it is guided into proper position along the groove 35 over the surface 4% of the bridging portion 3 2, over the surface 55 of the first projection 49, then over the convex bottom 42 of the intermediate bridging portion 34, over the beveled surface 56 leading to the surface 55 on the other projection 49, and finally over the surface 41 of bridging portion 33. The spacing is such and the thickness of the key 59 is enough to cause it to follow the undulating movement described on insertion and to remain in a wavy position as shown in FIG. 2. Not only does the key 59 securely hold the journal guide 47 in position but also it does so with a biasing action and thus prevents any rattling that might take place if the key 59 were loose.

FIGS. 13, 14, 15 and 16 show another embodiment of the invention. It is intended for use in the construction of railway car journal boxes 14- when they are originally manufactured rather than for addition thereto as is the case for the construction previously described and illustrated in FIGS. 1 to 12 inclusive. Insofar as possible the same reference characters will be employed in FIGS. 13 to 16 that were previously used.

Referring particularly to FIG. 16 it will be noted that the upper and lower guide bosses 66 and 67 are cast integrally with the vertical side wall 117. Similar bosses are cast integrally with the vertical side Wall 18 and need not be described further. The guide bosses 66 and 67 are formed with central recesses 68 and 69 for receiving bosses 7i) and 71 that are formed integrally along the upper and lower edges of an adapter plate 72 that preferably is a steel forging. As shown in FIGS. 13 and 14 of the drawings the adapter plate 72 is welded as indicated at '73 and 74 to the upper and lower guide bosses 66 and 67. After the welding operation is performed at '73 and 74, the side frame is annealed to relieve any stresses that might have been set up because of the welding operations.

FIG. 14 shows a cross section of the adapter plate 72. It will be noted that it is provided with a convex surface 77 which faces away from the axis 13 0f rota '5 tion of the railway car axle 10 and forms the bottom of a groove 78 the sides of which are provided by the guide bosses 66 and 67. The groove 78 corresponds to the groove 35 previously described.

Mounted on each journal guide support provided by the upper guide bosses 65 and 67 and the adapter plate 72 is a journal guide 81. Preferably it is formed of press forged bronze and it has a bearing face 82; which is positioned adjacent the surface of the axle journal 11 in a manner similar to that described for the bearing face 48 described hereinbefore. Each journal guide 81 includes projections 83 that are located beyond the ends of the adapter plate 72. The projections 83 are connected by side walls 84 to the central portion of the journal guide 81. The projections 83 have surfaces 85 which face toward the axis 13 and together with the surface 77 of the adapter plate '72 provide a longitudinally extending aperture parallel to the axis 13 for the purpose of receiving a key in the manner described previously. In order to facilitate application of the key the projections 33 are beveled as indicated at 86 and '87 on opposite sides of the surface 35. The key is indicated at '88 and, as previously described, it is formed of spring steel and is a flexible resilient elongated member. Because of the provision of the convex surface 77, the aperture defined thereby and by the surfaces 85 is offset at its intermediate portion from the end portions with the result that, as shown in FIG. 14, the key 8% extends along this aperture in an undulating manner.

At one end the key $8 is provided with a head 39 having a detent 9i} that is arranged to interfit with a groove l which is formed in a stop 92 that is cast integrally with the respective side walls 17 or 18. Since the detent 9d interfits with the groove 9l, movement in either direction of the key 33 is prevented. The other end 3 of the key 8% is rounded to facilitate entry into the aperture provided along the bottom of the groove 7%.

With a view to limiting the extent of downward movement of the journal guides 81 when they are inserted, stops 94 are cast integrally with the respective side walls 17 and 18 at the ends of the lower guide boss 67. The projections 83 engage the upper sides of the stops 9 s when they are assembled in the manner previously described and thus serve to locate the journal guides Ell for insertion of the key 88 in the undulating manner. An inclined surface 96 is provided for each stop 92 to facilitate the insertion of the key 33 and particularly to deflect the detent 9i to a position where it can enter the respective groove 91.

Since the application of the journal guides '31 in the assembly shown in FIGS. l3, l4 and 15 is essentially the same as described for the preceding figures, it will not be repeated.

Since certain further changes can be made in the foregoing constructions and different embodiments of the invention can be made without departing from the spirit and scope thereof, it is intended that all matter shown in the accompanying drawings and described hereinbefore shall be interpreted as illustrative and not in a limiting sense.
